Filter by:This study will explore ways to improve the effectiveness of patient Self Management at a time when genetic test results guide new treatments that will dramatically increase the possibility of cure of the hepatitis C virus.The study will also focus on the interactions between provider and patients and the ways that technical work, adaptive work and adaptive leadership foster patient self-management.This proposed 2 year exploratory mixed-methods 12 longitudinal case study will explore patients' and providers' explanations for how and why they engage in technical work, adaptive work, and adaptive leadership and the ways in which these strategies promote or pose barriers to patients' self-management of Chronic Hepatitis C in the context of the new genetic test results and treatments. Specific aims are to: 1: Examine how technical work, adaptive work and adaptive leadership influence patients' perceptions of their likelihood of cure and how this work relates to self-management during 12 to 24 weeks of treatment for Chronic Hepatitis C. Research questions are: 1.1) How do patients describe their interactions with the providers? 1.2) How do these interactions shape patients' perceptions of the likelihood of cure? 1.3) How do patients' understanding of their interactions with the provider promote the use of or pose barriers to self-management during treatment? AIM 2: Describe providers' use of technical work, and adaptive leadership approaches during clinical encounters,to include nurse education visits. Research questions are: 2.1) What technical work, and adaptive leadership approaches do providers use when sharing treatment information with patients during the clinical encounters. 2.2) What explanations do providers give for how and why they use technical work and adaptive leadership approaches? AIM 3: Describe the trajectories of illness perceptions(Control/Cure sub-scale - Illness Perception Scale), symptoms (M.D. Anderson Symptom Inventory) , viral load, and self-management (Patient Activation Measure) in relation to patient and provider reports of technical work, adaptive work, and adaptive leadership from the index clinical encounter to the follow-up treatment response encounter (ranging from 12 to 24 weeks).
Treatment of hepatitis C virus (HCV) infection was carried out using pegylated interferon (PEG-IFN), ribavirin (RBV) and vitamin D (vit D) for 48 weeks in HCV genotypes 4a subjects. The purpose of this study is to determine the effect of vitamin D on liver affection in such patients.
The purpose of this study is to evaluate the safety and antiviral effect of multiple doses of ABT-493 and ABT-530 in adults with genotype 1 HCV.
This is a multi-part study to evaluate the safety, tolerability, and pharmacokinetics (PK) of uprifosbuvir (MK-3682/IDX21437) in healthy participants and in participants infected with Hepatitis C virus (HCV) genotype (GT)1-GT6. The effect of food on the PK of uprifosbuvir will be evaluated. The antiviral activity of uprifosbuvir will also be assessed in HCV-infected participants.
Hepatitis C is the leading cause of chronic liver disease and cirrhosis in United States veterans. Cirrhosis is associated with impaired antibody responses and increased risk of bacterial infections. We have recently identified that cirrhosis is associated with abnormalities of memory B-cells, cells that make antibodies and help protect against bacterial infections. We have identified that chemicals associated with gut bacteria might play a role in causing these B-cell abnormalities. It is well known that gut bacteria have increased access to the blood in individuals with cirrhosis, a process called bacterial translocation. We hypothesize that reducing bacteria counts in the gut by using poorly-absorbed antibiotics (also known as selective gut decontamination) will partially reverse losses of memory B-cells in cirrhosis by reducing bacterial translocation.
The purpose of this study is to evaluate the antiviral efficacy of Boceprevir-based therapy for the treatment of genotype 6 chronic hepatitis C infection. Boceprevir has recently been approved for the treatment of genotype 1 chronic hepatitis C infection. Recent in vitro studies suggest similar efficacy against genotype 6 chronic hepatitis C infection. The investigators therefore hypothesise that: i) Boceprevir is a potent inhibitor of genotype 6 hepatitis C replication in vivo. ii) Boceprevir in combination with pegylated interferon-alpha and ribavirin for 24 weeks will cure a high proportion of patients chronically infected with genotype 6 chronic hepatitis C infection.
The primary objectives of this study are to assess the safety of ABT-450/r/ABT-267 with and without ABT-333 coadministered with and without ribavirin (RBV) for 12 and 24 weeks in HCV GT1- or 4-infected participants with HIV-1 coinfection and to evaluate the percentage of subjects achieving HCV ribonucleic acid (RNA) < lower limit of quantification (LLOQ) 12 weeks following treatment.
Grazoprevir (MK-5172) and Elbasvir (MK-8742) were studied as the principal components of combination oral therapy for hepatitis C virus (HCV). The study examined the pharmacokinetic (PK) profiles of Grazoprevir and Elbasvir following 10 days of dosing in participants with end stage renal disease (ESRD) on hemodialysis (HD) or participants with severe renal impairment. Both groups were compared to healthy matched controls.
The purpose of this study is to evaluate the safety and efficacy of ABT-450/ritonavir/ABT-267 (ABT-450/r/ABT-267; ABT-450 also known as paritaprevir; ABT-267 also known as ombitasvir) and ABT-333 (also known as dasabuvir) coadministered with ribavirin (RBV) in hepatitis C virus (HCV) genotype 1-infected adults taking methadone or buprenorphine ± naloxone.
This dose-escalating study is to evaluate the efficacy and the safety of different doses of a new bio-product Pegylated Recombinant Consensus Interferon Variant Solution for Injection (PEG-IFN-SA) and Ribavirin（RBV） in the treatment of Chronic hepatitis C who have not been previously treated with Interferon(IFN) by exploring the dose-effect relationship, while identity the optimal dose for phase Ⅲ study. In addition, population pharmacokinetic method is adopted to assess the pharmacokinetic behavior, individuals / intra-individual variability, and the possible factors for further study.
